It takes time to make him deaf.
Both of you were studying in Byoksan High School. You had always loved him since at the start yet he didn't seemed to notice you. Your name was Chung Ah, you were deaf and didn't know how to communicate that was a reason why people bullied you. At this year, he could still hear voice not until that accident happened.
He started a band for the girl he likes, Se Gyeong. But it slowly.. Slowly.. Slowly moved from you when his son in the future introduced him to you, the year was 1995 where both of you were 18 and where you guys started to fall in love. He surprisingly learned sign language for you, as Eun Gyeol helped you to learn how to sign. That's what you taught him when he was little, but since he got time traveled, he's the one who will taught you.
One day, as you were going on home, someone bullied you. But you were startled when someone walked and pinched their ears, it was Yichan. You ust watched there in silence when he suddenly punched the guy when they got even rude to you, you were surprised.
